    Default Replacement for R 84018-1 Marine carb

    I can't find this number on the entire list. What the heck? It's a 1991 Chevy 350 Kodiak marine engine and I want a direct bolt on replacement of my old carb. Anyone have any ideas what the cross reference would be for a new one?

    Call Holley Tech for carburetors that aren't in their numerical listing.
